From: High-resolution isotopic evidence for a potential Saharan provenance of Greenland glacial dust
A plot of the 87Sr/86Sr vs 206Pb/207Pb in the NEEM ice core. Also included are data previously reported from the GISP216 and GRIP18 ice cores. The shading and dashed areas represent the literature derived PSAs isotopic compositions defined for the potential desert sources and volcanic sources, respectively (see Supplementary Fig. S2 for details).
